3.14.6 Custom calibration buffers

You can define five of your own calibration buffers which can then be

used for calibration with automatic buffer recognition. The buffer

series can be selected in the CAL (calibration) command as the Custom

buffer series (see Section 4.7).

Open the dialog Templates/Custom calibration buffers.

Enter the pH of the first buffer under Buffer 1.

Use Temp.table to open the temperature table for this buffer. The

temperature table shows the pH values for the buffer at

temperatures from 0 to 95 °C.

Use [Edit pH value] to enter the pH values for the temperature

range in which you perform your pH calibration and pH

measurement. In the dialog [Temperature table/Edit pH value]

you can change directly to the next temperature. If you do not know

the pH values for individual temperatures, these will be calculated

automatically by linear interpolation.
